I've been playing H5 for more than ten years. The most annoying part of the game is when you have 8 heroes and you have to pass all your artifacts/troops from the very first hero to the very last hero in one turn.

Just wondering if there has been a fix to this issue? It would be a great time saver / life saver.

H3 got this HD+ Patch which allows one-click swapping of artifacts/troops between two heroes. See screenshot here.
